Combustible
Gas
Combustible gases present a explosion hazard when the gas
concentrations are between the lower explosive limit (the point at
which the amount of
combustible gas mixed with oxygen could generate and explosion) and
the upper explosive limit (the point at which there is too much combustible
gas and not enough oxygen to generate and explosion). Each gas has
its own Lower Explosive Limit, for instance, for
Methane, 100%LEL is equal to 5% by volume of Methane.
Sierra Monitor manufactures a variety of detectors for Combustible Gas for various applications. Our combustible gas sensors are available using either a Catalytic Bead sensor, Infrared sensor or a Solid State Semiconductor sensor depending upon your need.
- If the combustible gas is in the low PPM range you can use the Sierra Monitor 4100 Series sensors using Solid State Semiconductor Sensors.
- If you require a catalytic bead sensor with a 4-20 mA output signal to interface to PLCs and other device.
- If you require a catalytic bead sensor with 4-20 mA, digital display, non-intrusive calibration, relay output, and Modbus output
- If you require a catalytic bead sensor for a plant-wide monitoring system incorporating a wide variety of features including non-intrusive calibration, variable alarm/control options, serial output, WebServer, remote display and more, then use the Sentry system.
- If you require an Infrared gas sensor module with minimal maintenance, 4-20mA output, Sentry system interface, Modbus communication, digital display and alarm relays in one convenient package, then select the 5100-28-IT Gas Sensor Module
